# ==== Purpose ====
#
# Check requirements and regressions related to SOURCE_POS_WAIT.
#
# ==== Requirements ====
#
# R1. SOURCE_POS_WAIT should timeout as required
# R2. SOURCE_POS_WAIT should return an error if the replication applier
#     thread is stopped while the function is waiting.
# R3. SOURCE_POS_WAIT should return NULL when replication is not configured.
# R4. When negative timeout is given, SOURCE_POS_WAIT should return
#     error if sql_mode contains STRICT_ALL_TABLES; warning otherwise.
# R5. SOURCE_POS_WAIT should allow fractional seconds for the timeout;
#     it should not truncate 0.1 to 0 and wait without timeout.
# R6. SOURCE_POS_WAIT should accept two, three, or four arguments.
